One man, thought to be an anti-Morsi protester, appears to be pulled from a water tower on the roof, before being beaten.

The father of one of the victims, Hamada Badr, said his son was stabbed before being thrown from the roof.

The amateur video shows another two men being pushed from the water tower onto the roof.

Morsi supporters appear to beat the lifeless body of one of the men. The Telegraph has edited this section from the original video because of its graphic content.

A third man is seen falling from the water tower. According to security officials, one man survived.

Another amateur video posted online shows the violence from a different angle.

The videos appeared consistent with reporting from the area.

The violence is believed to have come after the Muslim Brotherhood's supreme leader, Mohammed Badie, issued a fiery speech on Friday to tens of thousands of his supporters in which he told them, "God make Morsi victorious. ... We are his soldiers. We defend him with our lives."

Following that speech, thousands of Islamists marched in the streets and clashed with Morsi opponents in the heart of Cairo and elsewhere in Egypt, leaving more than 30 dead and 200 injured.
